Abstract
Endoscopic transpapillary gallbladder drainage (ETGBD) is a difficult procedure to perform, and its technical success rate is reportedly lower than that of percutaneous transhepatic gallbladder drainage (PTGBD). Therefore, ETGBD is regarded and positioned as an alternative to PTGBD, and advanced techniques and tips are often needed for a successful ETGBD. ETGBD is classified into two types, namely, endoscopic naso-gallbladder drainage (ENGBD) and endoscopic gallbladder stenting (EGBS). The selection of ENGBD or EGBS should be decided after carefully considering the situation and status of the patient as well as after a detailed examination and treatment planning for the patient. Importantly, prospective studies involving a large number of patients for long-term EGBS are needed. ETGBD is a useful alternative to PTGBD and should be performed at institutions with skilled endoscopists. In this section, we describe the status of ETGBD and provide valuable technical tips in effectively performing ETGBD.
